I was testing source:madwifi/[EMAIL PROTECTED] on an IXP425 in an
[http://www.gateworks.com/products/avila/gw2348-4.php Avila from
Gateworks]. I am using kernel version 2.6.18.4 on ARM in big endian mode.
I have two mini-PCI radios, an [wiki:Compatibility/Ubiquiti#XtremeRange2
XR2] and an [wiki:Compatibility/Ubiquiti#XtremeRange5 XR5] from Ubiquiti.
Both are based on the 5212.
I have two VAPs created as APs. I noticed over time my free memory kept
decreasing. No applications had high usage in top. A bisectional search
lead me to r3401. This changeset sets the bf_node and bf_skb and takes a
reference on the bf_node. The problem is that it then calls ath_tx_start
which does the same starting at
[source:madwifi/trunk/ath/[EMAIL PROTECTED] line 7543].
This leads to an extra reference being taken that is never removed.
